  • Detection And Prevention Of Errors In Transmission (AREA)

Abstract

PURPOSE:To improve the reliability of data transmission by adding a parity bit formed by exclusive OR of adjacent data among data of plural bits being source data and coding the result so as to apply error detection based on the value obtained through the combination of different parity bits and data at the reception side. CONSTITUTION:Data D1-D3 are source data and each consists of 8-bit. The parity bits P1-P3 in 8-bit formed by the exclusive OR of adjacent data are added among the data D1-D3. They are arranged as P1, D1, P2, D2, P3, D3 as shown in figure and they are coded and sent to the reception side. The reception side applies the decoding to them and checks the parity bit to discriminate the presence of an error. That is, when only one parity bit is correct and others are not correct, and when the value obtained from the different combination of the data and parity bit is equal, it is regarded as a correct data, which is used for the correction. Thus, after code correction is applied by BCH or Hargelburger, the code correction is applied newly among the parities and data.
